Usage Information
The show crypto ipsec policy command output displays the AH and ESP
parameters configured in IPsec security policies, including the SPI number, keys, and
algorithms used.
When configured in a helper-reject role, an OSPFv3 router ignores the Grace LSAs that it
receives from a restarting OSPFv3 neighbor.
